While Emira gets a pass due to being at Dr. Bride's clinic, Sioux and Veronica are the only other LOWTH members who don't participate in interrogating Cross with the rest of the team.
I.M.P. was meant to appear earlier where Piniet would've hired them to assassinate Luz. This was changed to Loona getting trapped on the Isles which thematically fit the story better.
